Avoid a depleted daily budget

If you have a limited budget, you want to make the most of every cent you spend on your advertising campaign. When your budget is limited, your ad might not show as frequently as you'd like -- or might not show at all. Instead of discontinuing your campaigns and missing out on clicks, or spending more than you can comfortably afford, we'll share some techniques for spending your budget more effectively:

Lower your bids for campaigns that are "limited by budget," potentially reducing the average cost per click.

Let AdWords automatically bid for you to get as many clicks as possible with your campaign's current daily budget. (Note that this feature isn’t available for AdWords for video campaigns.)

Lower your bids in campaigns that are "limited by budget"

While counterintuitive, slightly lowering your bids in campaigns that are "limited by budget" could potentially help you earn more clicks. Lowering bids for budget-constrained campaigns could reduce the average amount you pay when someone clicks your ads, with the potential for your budget to go further and get more clicks. Lowering bids too much, however, could result in fewer clicks if your bids are no longer competitive. If you choose to decrease your bids, check your campaign a few days later to ensure that you haven't lowered your bids too much. Learn how to edit your bid

Let AdWords automatically bid for you

An alternative to lowering your bids yourself is to allow AdWords to automatically adjust your bids for you. When AdWords automatically sets bids for you, changing your keyword or placement maximum cost-per-click (CPC) bids, it'll still stay within a target daily budget that you've set for that campaign.

Change your delivery method from "Accelerated" to "Standard"

Accelerated delivery is likely to use up your campaign's daily budget early in the day. This is because accelerated delivery shows your ads until your budget is reached. "Standard delivery" is more optimized, which means that the delivery of your ads is spread more evenly throughout the day.

If you're using manual bidding, by default your campaign will be set to "Standard delivery." It's not possible to use "Accelerated delivery" with automatic bidding.

In the "Bidding and budget" section, click + Delivery method (advanced) and then click the Edit link.

Choose "Standard: Show ads evenly over time."

Click Save.

Find your campaign's recommended budget

AdWords shows recommended budgets for campaigns that repeatedly meet their daily budget but have the potential to earn more clicks and impressions. You can use these recommendations to estimate how a new budget may improve the visibility of your campaign's ads. The recommendations are based on the following factors:

Recent campaign performance

Current campaign budget

Keyword list

Campaign targeting settings

AdWords won't display a recommended daily budget if you rarely meet your daily budget, or if your campaign has limited data. If you don't see a recommended budget, and you know your ads aren't being shown as often as they could because your budget is limited, you might want to consider raising your budget to an amount that you're comfortable with.
